All dogs are going to -- keep in mind that all dogs are of different temperaments and different sizes and shapes. As I show you the hand strokes that you will use, you can modify those hand strokes and the pressure that you use to match your dog size and sensitivity level. This has been the introduction to how to massage your dog, and in the next sequence we will go over the basics of canine massage.
Some studies have shown that your deep sleep should at least be 20% of your overall sleep. It means that since most adults need 8-9 hours of sleep, they will need about 1.6-1.8 hours of deep sleep to feel fully functional next day.
Usually sleepers pass through five stages: 1, 2, 3, 4 and REM (rapid eye movement) sleep. These stages progress cyclically from 1 through REM then begin again with stage 1. A complete sleep cycle takes an average of 90 to 110 minutes, with each stage lasting between 5 to 15 minutes. The first sleep cycles each night have relatively short REM sleeps and long periods of deep sleep but later in the night, REM periods lengthen and deep sleep time decreases.
